1662550 - Firefox hangs on startup when restoring tabs and displaying password dialog for proxy [@ __pthread_cond_wait | _MD_WaitUnixProcess | nsAuthSambaNTLM::Shutdown]

Status: NEW

(Firefox :: Session Restore, defect)

Description

[Jens Müller (:tessarakt)]

Sometimes when I start Thunderbird and restore the tabs from last session (sorry, not sure if automatically or through the menu - I'll hopefully remember next time), a password dialog for my company's proxy is shown, but the dialog (as well as the main Firefox window) are unresponsive.

The system tells me that FF is unresponsive and offers me to terminate it.

I crash FF by sending SIGABRT (kill -6), which resulted in this crash report: https://crash-stats.mozilla.org/report/index/bb925370-cd84-4f47-9ffb-c589c0200901
